This removes the path-based dependencies on the `zcash_note_encryption`
crate in favor of using versioned dependencies locally. This better
reflects the future state in which `zcash_note_encryption` is factored
out of the workspace and maintained in a separate repository.
The `halo2_proofs/multicore` flag must be disabled when running wasm
builds; this ensures that we do not accidentally include it as a
transitive dependency when building with `--no-default-features`.
The MSRVs of the component crates are left as-is, partly because our
dependencies don't require us to bump them, and partly because those
crates have no pending changes and are relatively stable. We also plan
to split the component crates out into a separate repository, where it
will be easier to have a separate MSRV.
Closeszcash/librustzcash#759.
The change selection algorithm has the most useful information for
determining whether or not a note is dust, so this adds a new error case
to `ChangeError` that allows the change selection to report the presence
of input notes without economic value back to its caller.
This adds a set of abstractions that allow wallets to provide
independent strategies for fee estimation and note selection, and
implementations of these strategies that perform these operations in the
same fashion as the existing `spend` and `shield_transparent_funds`
functions.
This required a somewhat hefty rework of the error handling in
zcash_client_backend. It fixes an issue with the error types whereby
callees needed to have a bit too much information about the error
types produced by their callers.
Reflect the updated note selection and error handling in zcash_client_sqlite.
This is to replace the database mutations in the Android SDK. It is
placed behind an `unstable` feature flag until we are satisfied that it
is suitable as a general-purpose API (or replace it).
This replaces the current wallet initialization code with a migration
that brings the database up to the state produced by release 0.3.0.
A subsequent commit will add migrations that correctly produce the
database state as of zcash/librustzcash@602270cb1f.
Fixes#369
`protobuf 2.26` raised its MSRV to 1.52.1, which we are now above.
`protobuf 2.27.0` raised its MSRV to 1.55.0, but this was reverted in
`protobuf 2.27.1`. In any case, it's clear this dependency bumps MSRV in
minor releases, so we should use tilde requirements for it.
